UNITE STATES PATENT OFFICE.

OLIVER S. PLUMMER AND JOHN M. WOOD, OF RICHMOND, INDIANA.

VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent No. 328,609, dated October20, 1885.

(No model.)

To all whom it may concern.-

Be it known that we, OLIVER S. PLUMMER and JOHN M. WVooD, citizens ofthe United States, residing at Richmond, in the county of XVayne andState of Indiana, have invented certain new and useful Improvements inVehicle-Springs, of which the following is a specification, referencebeing had to the accompanying drawings.

Our invention relates to buggies and light vehicles.

Our invention consists in the peculiar construction and combinations ofthe devices, hereinafter described, for hanging the body of a buggy orcarriage to the running gear of the same.

In the drawings, Figure 1 is an inverted plan view of our improvementsand their connections. Fig. 2 is a perspective view of a cone-shapedjournal. Fig. 3 is a central longitudinal vertical section of Fig. 1.Fig. 4 is a side elevation of a hanger-arm.

In Fig. 1, A A represent the ordinary form of side bar in use in buggiesand carriages, and O O the axles.

B B are the body-sills, and D D are crosssills, to which the spring andits attachments are fixed.

E E are longitudinal bars curved laterally inward at their centralportions, and secured at their ends to the cross-sills D D by bracketsattached to the under surface of the same near its ends.

The ends of the curved bars E Eterminate in a screw-thread, c, and havetheir bearings in a taper or cone-shaped journalbearing, a, which isinserted in the brackets s s, the journal-bearing at having a squareopening, which fits upon the bar E, allowing the bar E a partialrevolution along with the journal-bearing a in the bracket 8.

F is a curved or cradle spring, and is placed centrally between the sidebars, A A, secured to the cross-sill D at each end by a hinged bracket,02. A cross, 2, is rigidly attached to the center of the spring F, atthe apex of its curve, having lateral arms 2' i, projecting laterally,to which are affixed the hinged couplings m, which connect the arms 2 zwith similar lateral armsyi i, by means of axis-pins 0 0, constituting ahinged connection between the spring F and bars E E, at or near thecenter of each and at right angles to both.

G G G G are curved hangerarms, as seen in Fig. 4, provided with a squareopening, h, at one end to receive the curved bar E, and a hinged clip atthe opposite end, K, by which it is attached to the side bar, A. Thesehanger-arms are secured to the curved arms E E, near their ends, as.seen at h h h h, and support the weight of the body of the ylhescrew-thread c, on the outer end of the bar E, is furnished with ascrew-nut, d,which is in contact with the end of the cone-shapjournal-bearing a, and by turning home the nut the journal-bearing a isforced into the opening in the bracket 8 to take up any play or lostmotion that may occur from the wearing away of the hearing or thebracket.

The spring F receives the entire weight of the body at its center and atits ends, and at whatever place within the confines of the body or itssill the weight may be placed the whole body is equally depressed, theparts having a tendency one with the other to distribute and equalizethe pressure throughout the length of the spring F.

Having thus fully described our said invention, what we claim as new,and desire to secure by Letters Patent, is

l. The spring F, provided with arms t t and hinged brackets n n,constructed and operating substantially as herein described.

2. The curved arms E E, provided with journal-bearings a a, screw-nut d,and screwthread 0, when combined with the spring F by hinged couplings mm and arms 2" i, as herein described.

3. The combination of the side bar, A, the hanger-arm G, and bar E, withthe spring F, in the manner and for the purposes herein set forth.

In testimony whereof we affix our signatures in presence of twowitnesses.

OLIVER S. PLUMMER. JOHN M. WOOD.
